The recent improvement of Latin-American sociology moves towards reinforcing and giving value to its own scientific production. This enables the consolidation of the self interpretation of its social reality, capable of promoting the development of several potentialities in Latin-American societies. The objective of this text is to recover the practical and epistemological positions of Alberto Guerreiro Ramos published in different media and recognized as a "sociological reduction". Based on Guerreiro Ramos' standpoints presented in the 2nd Latin-American Conference in Sociology, this paper aims at relating the terms of sociological reduction to the post-colonialist imagination, observing methodological proximities and distances from the craft of sociology and the innovations provided by the author, bearing in mind the sociological reduction.
